    Bouncing assembly

    Alan Thomason

      I have created a very simple assembly for the purpose of better understanding how to approach a more complex problem.  I have a mechanism for which I wish to simulate an impact, but also settles together and then needs to simulate friction. 

       

      So, a cube is shown dropping onto a plate.  I wish to have the cube bounce and have it come to rest.  I have tried all three solvers available, as well as various combinations of materials.  So far, I am unable to achieve both.  If anyone has any hints it would be most appreciated.

       

      Thanks in advance...

          What exactly is the problem your trying to figure out?

              The end goal is a more realistic simulation of a door latch mechanism, which involves impact contacts, but also sliding and static friction on the same surfaces.  I was going back to a rudimentary scenario in hopes of learning lessons that I could apply to the more complex scenario.  I got stuck quite early on with the cube bouncing pretty realistically but then having the cube sit and spin on top of the plate.  Since my goal was to combine a coefficient of restitution and contact friction anyway, I wanted to put friction in place, assuming that the cube will then come to a rest. 

               

              Attempts to have both friction and coefficient of restitution in place simultaneously have thus far not been successful, with the simulation crashing as soon as contact is made.
